I agree with Cashs mom. Just about any color can be considered a neutral if it is muted down and not saturated. Think Japanese taupes. I consider them a very neutral palette but they contain many muted shades of color with occasional pops of a saturated neutral like rust, indigo blue or brown.
Google images of "Neutral color quilts" and you will be amazed. Now some of the images are not at all what I would consider neutral but others that I would have touches of turquoise, orange, peach, green and yellow in them. However the overwhelming majority are done in semi-monochromatic color schemes of beiges, browns, tans, creams, grays, soft golds and ivory.
